CAR-COUPLING.

Specification of Letters Patent.

Patented Nov. at, 1913.

Serial No. 719,734.

1/ '0 all whom it may concern Be it known that I, YVILLIAM R. H. GareWELL, a citizen of the United States, residing at Jamesburg, in thecounty of Middlesex and State of New Jersey, have invented certain newand useful Improvements in Gar-Couplings, of which the following is aspecification.

My invention relates to improvements in car couplings, the object of theinvention being to provide an improved construction of coupling headhaving separable ears receiving the pivot pin of the knuckle, so that inthe event one of these ears should break, it can be replaced withoutdiscarding the coupling.

A further object is to provide a coupling head which is capable of usein connection with any of the well known types of knuckle in generaluse.

Couplings as ordinarily made are pro vided with ears which are integralwith the head. These ears frequently break, and necessitate thediscarding of the entire coupling. The knuckles of car couplings alsobreak, and as there are many different types of coupling in general usewith knuckles of aspecial make to fit such couplings, when such knucklesbreak, it is necessary to find a like knuckle for the coupling,necessitating a large variety of knuckles to be kept in stock or elsethe repair of the car delayed.

It is the purpose of my invention to provide a coupling which hasremovable or separable cars so that in the event of the breakage of oneor both of the cars, they may be replaced and also to provide a carcoupling with a head and locking means of a construction which permitsthe use of any of the well known types of. knuckle in general use.

With these and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings: Figure 1 is a broken plan viewillustrating my improvements. Fig. 9. is an end view of the head withthe knuckle removed. Fig. 3 is a view in longitudinal section on theline 33 of Fig. :2 but showing the knuckle in place. Fig. 4 is a view intransverse section on the line H of Fig. 3. Fig. 5 is a detailperspective view of the locking block. Fig.

6 is a detail perspective view of one of the ears, and Fig. 7 is asimilar view of the washer.

My improved car coupling comprises a draw bar 1 having an integral head2, and

this draw bar and head may be made of which removable ears 5 aresecured. These ears are in the form of blocks with central openings 6,and said blocks at one end have fiat faces 7 which bear against the flatface' 4 of the head.

Integral angular extensions 8 are provided on the cars which arepositioned in the angular openings 9 in integral enlargements 10 on theupper and lower portions of the head. The free ends of these extensions8 are provided with cylindrical screw-thread ed lugs 11 which areprojected through openings 12 in angular washer plates 13 and nuts 14are screwed onto the lugs against the plates. By reason of such aconstruction, the ears are rigidly secured to the head and are heldagainst any turning movement and they are adapted to receive the knuckle15 between them, said knuckle being pivotally supported by the ordinarypin 16.

The knuckle, as is customary, is provided with a tail 17 which swingsinto the head, and this tail is locked against movement by my improvedlocking block 18. The block 18 is positioned in a recess 19 in the topof the head, and is pivotally connected at one end to the head by meansof a transverse pin 20. This block 18 is provided with perforated lugs21 which are connected by a link 22 with a clevis 23 on top of the headand through the medium of a chain 25 said block is adapted to beelevated to release the knuckle tail. The block 18 is provided with anintegral lateral extension 26 which r is movable in a transverse recess27 in the head, and this extension 26 normally rests upon the upper faceof the knuckle tail and holds the block in its normal locking position.By means of a locking mechanism of this kind, any ordinary form ofknuckle hav ing a tail may be used in connection with the head, hence,if the knuckle breaks, any ordinary knuckle may be placed in position inthe head and the coupling will be ready for use. Such a structuretherefore does not require a particular knuckle but is capable of useWith any of the Well known forms of knuckle. The block when elevatedmoves into the recesses 19 and 27 and is out of the Way of the tail ofthe knuckle, so that knuckles having tails of Various shapes may besi'vung into the head and when the block falls, Will be securely heldagainst upward movement.

Various slight changes might be made in the general form and arrangementof parts described Without departing from my invention, and hence I. donot limit myself to the precise details setforth, but consider myself atliberty to make such changes and alterations as fairly fall. Within thespirit and scope of the appended claims.

Having thus described my invention, What I claim as newand desire tosecure by Letters Patent is:

1. A car coupling comprising a head havin enlargements at topand-bottom, said en argements having flat front faces, and openingsextending through the same longitudinally of the coupling, ears havingflat surfaces positioned against the enlargements, and integralextensions on saidear secured Within the openings in the enlargements,

substantially as described.

2. A car coupling comprising a head having enlargements at top andbottom, said enlargements having fiat front faces, and openingsextending through the same longitudinally of the coupling, ears hayingflat enses surfaces positioned against the enlargements, and integralextensions on said ears projected through the openings in the enlargements, devices securing the extensions in the enlargements, and saidopenings and said extensions angular in cross section, substantially asdescribed.

8. A car coupling comprising a head having enlargements on its top andbottom at one side, said enlargements haying flat faces and openingstherethrough, ears positioned. against the fiat face of the head,extensions on the ears projected through the openings, and means ontherear face of the enlargements securing the extensions in the openings, substantially as described.

at. A. car coupling comprising a head having enlargements on its top andbottom at one side, said enlargements having flat faces and. angularopenings therethrough, ears having flat faces positioned against theflat faces of the enlargements, angular eXtensions on said earspositioned in the angular openmgs of the enlargements, cylindricalintegral screw-threaded studs on the ends of said extensions, angleplates haying openings therein through which the lugs are projected, andnuts on the lugs pressing the angle plates against the rear faces of theenlargements, substantially as described.

. In testimony whereof I have signed my name to this specification inthe presence of two subscribing Witnesses.
